Payment Terms in Freelance Contracts: Red Flags and What's Standard UK
Published on
Standard payment terms for UK freelancers are 30 days from invoice receipt, the default set by the Late Payment of Commercial Debts (Interest) Act 1998 for business-to-business transactions. Most freelancers accept whatever payment terms their clients offer. Many end up with terms that are worse than the statutory baseline and don't know it.
The most common problem isn't payment period length. It's the trigger condition: the event that starts the clock. "30 days from invoice" is clean. "30 days from satisfactory completion" is not, because satisfactory is subjective and the clock doesn't start until the client decides it does.
Key Takeaways
The UK statutory default for B2B payments is 30 days from invoice. This applies even if your contract says something different that is less favourable
"Satisfactory completion" and "client approval" payment triggers are red flags. They give clients indefinite control over when the clock starts
You have a statutory right to charge 8% above Bank of England base rate on late invoices, plus fixed compensation of £40–£100 per invoice
A deposit of 25–50% upfront is standard practice for longer projects and worth requesting in your contract
Payment terms can and should be negotiated before signing. Most clients expect it
What are standard payment terms for UK freelancers?
The Late Payment of Commercial Debts (Interest) Act 1998 sets a 30-day default where no payment period has been agreed. Where the contract specifies a period, the agreed period applies, subject to a 60-day backstop for B2B terms longer than that (unless the longer term was expressly agreed and is not "grossly unfair to the supplier"). Statutory interest runs from the day after the operative period ends, not from day 31.
In practice, what you'll encounter:
14 days: Common for smaller agencies and solo clients; genuinely good terms
30 days: Standard and fair for most professional service engagements
45 days: Common in some industries (publishing, media, large corporates); borderline acceptable
60 days or more: A red flag unless the contract value is very large and compensates for the wait
The period alone isn't the issue. A 45-day period from invoice date is inconvenient but manageable. A 30-day period triggered by "client approval of deliverables" is a far bigger problem, because approval can be delayed indefinitely.
The most dangerous payment clause traps
The "satisfactory completion" trigger
What it looks like: "Payment shall be made within 30 days of satisfactory completion of the deliverables."
This is the most common payment clause red flag in UK freelance contracts. The clock doesn't start when you deliver the work. It starts when the client decides they're satisfied. There's no definition of what satisfactory means, no timeframe for the client to raise concerns, and no mechanism to trigger the clock if the client simply doesn't respond.
Lena, a freelance UX researcher in Manchester, completed a user research project for a financial services company. Her contract specified payment within 28 days of satisfactory completion. She submitted her final report. The client acknowledged receipt but said they were "still reviewing." She followed up twice. Four months after delivery, with no feedback and no payment, she had to threaten formal debt proceedings to get paid. The contract gave the client every legal basis to delay. She'd never have agreed to that clause if she'd known what it meant.
The "upon client approval" trigger
Similar to satisfactory completion but often with a more explicit approval gate: the client must formally sign off before the payment period begins. Where this is tied to a defined review process (comments within 10 days, approval within 5 days of revisions), it's manageable. Where it's open-ended, it's the same problem.
Retention clauses
Some larger clients (particularly construction, marketing agencies, and corporations) include retention clauses: they hold back 10–20% of the total invoice for 30–90 days after delivery. Retentions exist to provide an incentive for defect resolution. In practice, for freelance services, they're often a cash flow burden without a corresponding benefit.
If you see a retention clause, request either its removal or a clearly defined release trigger and maximum retention period.
"Net 60" without a statutory interest reference
A 60-day payment window sits at the upper limit of what the Act treats as standard for B2B contracts. If you agree to a 60-day window, statutory interest runs from day 61. The right to that interest is automatic and cannot be waived by a blanket clause: under sections 8 and 9, only a "substantial contractual remedy" specifically designed to compensate for late payment can displace it.
What the Late Payment Act gives you
Most freelancers don't know this: you have a statutory right to charge interest on late invoices regardless of whether your contract mentions it. You don't need a clause. You don't need to have discussed it. The right exists by statute.
Under the Late Payment of Commercial Debts (Interest) Act 1998:
Statutory interest rate: Bank of England base rate plus 8% per annum, calculated daily from the date payment was due
Fixed compensation per invoice:
£40 for invoices under £1,000
£70 for invoices between £1,000 and £9,999
£100 for invoices of £10,000 or more
Reasonable debt recovery costs: If you have to engage a solicitor or debt collection agency, you can claim reasonable costs on top of the above
You can include a clause in your contract that references these rights explicitly. This reinforces your position and makes it clear to the client that you're aware of your statutory entitlements. Or you can say nothing in advance and simply invoke the Act when a payment is late.
The Act applies to any commercial transaction between businesses in the UK. As a sole trader or limited company, you're covered.
What payment terms should you aim for?
Before signing, review the payment terms against this benchmark:
Clause | Aim for | Red flag |
|---|---|---|
Payment trigger | On delivery / on invoice date | "Client approval" or "satisfactory completion" |
Payment window | 14–30 days | 45+ days, especially with a subjective trigger |
Late payment | Explicit statutory interest clause | No mention of late payment at all |
Work in progress | All completed work paid within 14 days of termination | No provision for WIP on early termination |
Deposit | 25–50% upfront for projects over £1,000 | Zero upfront for long or complex projects |
The deposit point is worth emphasising. For projects over a few weeks in length, a deposit protects you against the risk of the client walking away mid-project and signals that the client has genuine intent to proceed. Many freelancers don't request deposits because they assume clients will object. Most clients expect them.
💡 Pro Tip: Add a simple late payment clause to any contract that doesn't include one: "Invoices not paid within [30] days shall accrue statutory interest under the Late Payment of Commercial Debts (Interest) Act 1998." This doesn't threaten the relationship. It states a legal right you already have.
How to negotiate better payment terms
Payment terms are among the easiest clauses to negotiate because there's a clear statutory benchmark to reference. You're not asking for special treatment. You're asking to align with what the law considers standard.
Three specific requests worth making:
1. Change the payment trigger
If the contract says "satisfactory completion" or "client approval," request: "Payment to be made within 30 days of the invoice date, which shall be raised on delivery of the agreed deliverables." This moves the trigger to delivery and the clock to invoice date, both objective and in your control.
2. Add a statutory interest clause
Even if you never intend to charge interest, including the clause signals that you know your rights. Clients who understand that late payment will carry a cost tend to pay on time.
3. Request a deposit for longer projects
For engagements over two weeks or £1,000, propose 25–50% upfront. Frame it as standard practice: "I work with a deposit for projects of this size to cover initial costs and time allocation." Most clients accept this without discussion.
One pattern worth flagging. A 60-day payment term sitting alongside an IP assignment that transfers on delivery is doubly bad: the client owns the work and has two months to delay payment, while your only leverage in a dispute (withholding the deliverable) is already gone. Raise both clauses in the same negotiation email.

What to do if a client pays late
Once an invoice is overdue, your steps are:
Send a polite reminder: confirm the invoice details, reference the payment date in the contract, and ask for a confirmation of when payment will be made
Issue a formal late payment notice: reference the Late Payment Act, state the interest accruing, and set a new payment deadline (typically 7 days)
Engage a solicitor or debt recovery service: for larger amounts, professional assistance often prompts payment more effectively than further correspondence
Small claims court: for debts under £10,000, the small claims track in England and Wales is relatively accessible and low cost. The equivalent in Scotland is the Simple Procedure (handled by the Sheriff Court) with a limit of £5,000.

Frequently asked questions
What are standard payment terms for freelancers in the UK?
The UK statutory default for business-to-business payments is 30 days from invoice. In practice, 14–30 days is considered fair for most freelance engagements. Payment windows of 45 days or more are common in some industries but are longer than the statutory baseline and worth negotiating where possible.
Do I have to accept 60-day payment terms?
No. Payment terms are negotiable. Clients can propose 60-day terms, but you're free to counter-propose shorter terms. If you agree to 60-day terms and payment arrives 60 days after the invoice date, you have no recourse for lateness. If you agree to 30-day terms and payment arrives at 60 days, you can charge statutory interest from day 31.
What is the Late Payment of Commercial Debts Act?
The Late Payment of Commercial Debts (Interest) Act 1998 is UK legislation that gives businesses the right to charge statutory interest on overdue invoices (currently Bank of England base rate plus 8%) and to claim fixed compensation of £40–£100 per invoice. It applies automatically to business-to-business transactions without needing to be mentioned in the contract.
Can I charge interest on a late invoice without a contract clause?
Yes. The Late Payment Act gives you the right to charge statutory interest regardless of whether your contract mentions it. The right is automatic for commercial B2B transactions. Including a clause that references the Act is good practice but not a requirement.
What is a "satisfactory completion" payment clause?
A payment clause where the clock starts not at delivery or invoice date but at the point the client confirms they're satisfied with the deliverables. Because "satisfactory" is subjective and undefined, clients can delay sign-off indefinitely without technically breaching the contract. It's one of the most common risky payment clauses in UK freelance contracts.
Should I ask for a deposit as a freelancer?
Yes. For projects over a few weeks or a few thousand pounds, a deposit of 25–50% is standard industry practice. It protects you against a client walking away mid-project, signals genuine intent, and reduces your exposure if payment disputes arise later. Most clients who engage freelancers regularly expect to pay a deposit.
